SilkParasite is a cyberespionage operation assessed with medium confidence as China-nexus that targeted government bodies across Central Asia. Seven remote access tool families were deployed, five of which were previously undocumented: DriveSilkRAT, CookiETagRAT, NomadRAT, GoginRAT, and NodeEdgeRAT. The toolset is small, modular, and professionally engineered with traces of AI-assisted development. Initial access occurred through malicious Microsoft Office documents delivered via spear-phishing, using regionally tailored lures impersonating government ministries. The operation leveraged DLL sideloading as the primary delivery mechanism and used Google Drive for command-and-control communications to hide within trusted services. Infrastructure analysis identified connections to China Unicom's backbone network, and operational patterns suggest a functioning software organization with maintained build pipelines and careful operational security.

Kaspersky identified a new .NET Native AOT communication module for Project CAV3RN, a sophisticated cyberespionage framework targeting Israel. This module replaces the previous HTTP/WebSocket component by exchanging commands through Outlook calendar events accessed via Microsoft Graph API. Commands and results are stored in a fixed time window (2050-05-13 22:00-23:00 UTC) using specific subject patterns to identify heartbeats, commands, and outputs. The module implements RSA and AES-GCM encryption for secure communications. If Microsoft Graph authentication fails, it retrieves replacement configuration settings through DNS AAAA record responses from actor-controlled nameservers. The infrastructure analysis and behavioral patterns suggest low-confidence attribution to OilRig (APT34), based on the use of Microsoft-hosted services for command and control and compromised regional infrastructure.
